nnvrcn FOR sEcuRmG AXLE-BOXES To AXLES.

Specification of Letters Patent.

Patented April 21, mos.

Application filed December 6, 1907. Serial No. 405,302.

To all whom it may concern:

Be it known that I, CLARENCE E. HEGK- .MAN, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in De-" drawings, forming. a part of this specification, and to the reference-numerals marked thereon. I

The present invention relates to devices for securing axle boxes to axles of the type in which a spring or other yielding element is interposed between said parts to take up end thrust in two directionsand it has for an object to provide animproved construction wherein the axle box may be adjusted to engage the yielding element in such a manner that the rotation of the box will not beretarded but all loose-movement or play will berevented. I i

nother object is to provide a construction in which the yielding device is so mounted that it will be withdrawn and held by the engagement with a screw threaded extension axle box when the latter is removed to' grease or oil the axle spindle.

To these and other ends the invention consists in certain-improvements andcombinations of parts all as will be hereinafter more fully described, the novel features. being pointed out in the claims at the end of the specification. In the drawings wherein is shown an embodiment of my invention, Figure 1 re resents a side view of an axle box arrange on one end of an axle, the axle cap being shown in section. Fig. 2 shows all arts of the invention in longitudinal section except the axle; and Fig. 3 is a sectional view on line .a-a'Fig. 2.

Referring more particularly to the drawings 1 indicates a spindle portion of an axle which may have a reduced portion 2near one end to rovide a shoulder 'or abutment 3, the

ends of the spring This device is heldon the reduced portion by the axle nut 6 having 7 and serving as a removable abutment for the yieldin device. I Surroun ing the axle SPiIldlGflS the axle about these abutments.

outer end, forming a shoulder 10 which engages the inner end of the yielding device, the two movable abutments 5 of the yielding device having a diamet er almost equal to the diameter of the bore 9 so that the box turns The other end of the yielding device is engaged by an adjustable abutment 11 which is arranged within the axle box and preferably has external threads to engage with internal threads in the end of the box. lhis abutment is preferably in the form of a ring having notches 12 by which it may be turned to. be adjusted until both it and the abutment or shoulder 10- engage opposite ends of the yielding device, the engagement being'such that the axle box has no play but at the same time may turn or move the abutment away from the yielding device and not to move in the direction to compress the spring. I

Inv order to lock the movable abutment in its adjusted position and at the same time to. inclos the parts to exclude dust, I-employ an ax e ca 13 which engages the exterior of the axle 0x withthreads disposed n a direction opposite to the direction of the threads which connect the movable abutment 11'to the box. v By reason of the right and left handed threads connectin the a'butment and the cap -to the box an of an inwardly extending flange 14 or other portion on the cap which en agesthe movable abutment, the latter is o'cked against turning, due to the turning of the axle box in operation.

To remove the axle box the ca 13 is unscrewed, from the box and then t e nut 6 is taken off. The axle box is now withdrawn and the yielding device comes off also and is held within the box.

With this invention to take u for wear, it is only necessary to remove tie cap-,and when the box is removed there is no danger of misplacin the yielding device as it is held in the box etween the two internal abutments. I The yielding device is mounted to rotate box 8 which has an enlarged bore'9 at its on the axle so that should the ad'ustable abutment be turned so far that the evice is clamped between the abutments of the axle box, the latter may turn freely, although end play will be present.

I claim as my invention: a

1. The combination with an axle. and a yielding device surrounding the same, of an axle box having an internal abutment arranged to engage 'one end of the yielding device, and an adjustable abutment arranged within the box to engage the other end of the yielding device and movable to compensate for wear on both abutments.

-2. The combination with an axle and a yielding device surrounding the same, of an axle box having an internal abutmentv arranged to engage one end of the yielding device and internal threads, and an adjustable abutment movable on the internal threads to compensate for wear on both abutments and arranged to engage the other end of the yielding device.

3. The combination with an axle having a reduced end, a yielding device surrounding the reduced end, and a nut securing the device in place, of an axle box surrounding the axle having an internal abutment arranged to engage one end of the yielding device, and an adjustable abutment arranged within the box to engage the other end of the yielding device and movable to compensate for wear on both abutments.

4. The combination with an axle and a yielding device surrounding the same, ofan axle box having an internal abutment ar ranged to engage one end of the yielding device, an adjustable abutment arranged within the box to engage the other end of the yielding device, and a ca for the axle box having a portion arrange to engage the adjustable abutment to lock it in its adjusted position.

5. The combination with an axle and a yielding device surrounding the same, of an axle box having internal threads and an internal abutment arranged to en age one end of the yielding device, an adjustable abutment engaging the internal threads and. arranged to engage the other end of the yielding device, and a cap for the axle box having threaded engagement with-the latter, the threads being disposed in a direction opposite to the direction of the threads on the adjustable abutment, and said cap having a portion to engage the adjustable abutment to lock the latter in its adjusted position.

6. The combination with an axle having a reduced end, a yielding device surroundlng the reduced end, and a nut securing the device in 1glace, of an axle box surrounding the axle aving an internal abutment ar ranged toengage one end of the yielding device, an adjustable abutment arranged within the box to engage the other end of the yielding device,- and a cap for the axle having a portion locking the adjustable abutment against movement.
